| Abstract: | Surface of potassium titanate whiskers was modified with three kinds of coupling agents and got the materials named SMPTW,and then potassium titanate modified PU composites for terrace coating material was made from toluene diisocynate, polyether glycol and SMPTW. The effects of variety of coupling agents, SMPTW content on the mechanical and durability properties of potassium titanate modified PU composites were studied. The results showed that the tensile strength and elongation at break of the composite was 2.9 MPa and 340%, respectively. Af-ter accelerated aging test, the properties of the composite met the requirements of the athletic field. |
